I started to notice a clunk when I turned the wheel to the left which I though t was unusual. It concerned me that it sounded like a worn linkage or ball joint and the car had only 21,000 mile on it. Who informed me that there had been a bad lot of a steering linkage part put on certain Avalons that they couldn't identify. Therefore, no recall which disturbed me. I though Toyota was known for outstanding quality! the car now has 26,300 miles and there have been no further issues.
